' Referring to Figs. 1 to v6 inclusive, the

striping device herein shown by way of example comprises preferably ahollow supportr mg body 10 forming a reservoir 11 for containing thestriping fluid, such as paint or lacquer. removable cap or closure 12having a suitable air vent therein. The body 10 is provided with aforwardly projecting boss 13 which is tapped to receive a threaded plug1 1 having a central bore within which is fitted a feed tube 15. Theforward extension of the feed tube 15 forms a support for an applicatorbody 16 having a central bore to permit the applicator to be fitted ontothe end of the tube. Within the forward end of the tube 15 is secured aplug 17 forming a valve seat for a needle valve 18.

The striping device is grasped by the workman through the medium of ahandle or stock 19, the upper portion 20 of which is suitably mounted onand secured to the body 10. The part 20 of the stock has a centralopening 21, and through this opening and an opening 21a in the stockextends a trigger device 22. The upper end of the trigger is pivoted at23 to the body 20. Intermediate its ends within the opening 21. thetrigger is engaged by a spool 24: which is spring pressed against thetrigger by means of a compression spring 25. The tension of this springmay be adjusted by means of a screw plug 26 having a knurled head 26a.The spool 24 is fastened to the rear end of the needle valve 18. Fromthis construction it will be seen that when the workman presses thetrigger 22, the latter retracts the spool 24 andthereby the needle valve18, opening a passage through the valve member 17. The size of thisopening, and hence the amount of paint adapted to flow from thereservoir to the applicator, may be governed by adjusting the member 26relatively to the trigger member 22, resulting in varying the tension ofspring 25. The member 26 is at the same time adapted to provide anadjustable stop for the trigger, limiting as desired the range ofretraction thereform stripe with the desired flow Vii 7 the molding ingof so as to determine and regulate the flow of paint or lacquer to theapplicator. Hence, after a predetermined relative adjustment of theparts, the workman will obtain a uniof paint by fully retracting thetrigger device during the striping operation, and upon release thereof,the needle valve 18 will be shifted forwardly to close the passage,cuttingolf the flow of paint to the applicator.

The applicator body 16 is formed, in the presentinstance,with a pair offorwardly pro jecting pen nibs or blades 27 and 28. Leading from thechamber 16a, which is formed atthe end of the feed tube, 15, is a tube29 which extends centrally between the nibs 27 and 28 to the extremeends thereof. The forward portion 30 of the tube 29 is preferablyflattened and also somewhat flared and joins the points of the pen nibs27 and 28 as shown in Figs. 2 and 5. In this manner an applicator isformed in which the extreme ends ofthe pen nibs are joined by theflattened feed tube 30, and a narrow elongated orifice 31 for thedischarge of paint or otherfiuid is formed between the nibs.Consequently, the end of the feed tube as well as the ends of the nibsform the applicator proper, which may be curved or concave in shape, asillustrated, so as to conform to the curved edge of a belt line moldingor head.

The foregoing construction of the applicator is important in providing ameans for finishing ofi the edge of a stripe or painted area along theedge. of a molding or head M, see Fig. 1. As illustrated in this viewthe applicator is particularly adapted for filling in the unstripedportion 32 I along the upper curved edge of the molding M at thejunction of two areas having lacquer finishes of different colors orshades, producing a sharp and even border line between the color band onM and the contrasting color of the panel L. p

The applicator body 16 has a cylindrical bore which forms a snug fitover the feed tube 15, but permitting the applicator to be turned orrotated on the feed tube so as to locate the applicator nibs indifferent angular. positions, In Fig. 1 the applicator-nibs are inposition to form a stripe along the area 32 at the upper edge of themolding,-whereas in F 1g. 4 the applicator nibs are turned at rightangles or inverted to permit the blocking in of a stripe alon the loweredge32a of the molding M. In this manner the striping device may be usedalong the upper. or lower edgeof the molding without reversing theposition of the device in the hand of the workman.

Supported by the applicator body 16 and thestock or handle 19 is anadjustable bar 33 WhlCh is constructed to carry devices for accuratelypositioning and guiding the stripgun during operation. Fitting over the[wheel or cylindrical end of the body 16 is a ring 34 carrying anadjusting screw 36 and nut 36a. The screw extends through a verticalslot 37 in the upper half of the bar 33, and the latter is held in fixedadjusted position by tightening the nut 36a. The lower half of the bar33 is provided with a corresponding slot 37a and is adjustably connectedto a sleeve 38 fitting over a projecting lug 38a secured to the lowerend of the stock 19 by means of a set screw 39 extending through theslot37a.

Adjustable vertically on the bar 33 is a sleeve 40 which is supported onthe bar by means of an adjusting screw and nut 41 cooperating with theslot 37. The sleeve 40 carries a guide tube 42 within the bore of whichextends a yielding guide member or bar 43. This member terminates in aguide ring 44 adapted to contact along the edge of the molding M for thepurpose of guiding th striping device. The guide bar 43 is acted upon bya compression spring 45 and is connected to the tube or socket member 42by a pin and slot connection 46.

Carried by the bar 33 is a second sleeve 47 which is adjustablevertically on the bar through the medium of the guide slot 371 by meansof an adjusting screw and nut 48 cooperating with the slot. The sleeve47 has a transverse bore through which extends a spindle 49 having akeyway 49a into which projects the end of a set screw 50 for locking thespindle in adjusted position within the sleeve 47, The forward end ofthe spindle 49 is bifurcated to receive a guide wheel 51 jourualedtherein. The wheel 51 has a peripheral tire of rubber or other frictionmaterial and is adapted to travel over the surface of the panel Lbeneath the pen nibs and in position between the lower part of thehandle 19 and the panel so as to properly'position the pen nibs at therequired angle. The wheel 51 may be adjusted toward and from the handlestock 19 so as to properly determine the angle of the applicator andfeed tube 15. Consequently,by means of the guide 44 and the roller 51the guiding of the pen nibs over the surface being striped is nearlyautomatic, and the operation of the device is not dependent upon anyparticular skill of the workman. i
